problem with variable and function

[Alex Hall]

Below is pasted the function which is looking for the "funcs"
dictionary, as well as the dictionary. They appear in my py file in
this order, yet I get an error in nextMode() that "global name 'funcs'
is not defined". Oddly, the keys dictionary works fine; it is defined
above the nextMode function.

def nextMode():
 global HOTKEYS
 global HOTKEY_ACTIONS
 global mode
 global modes
 global modeNum
 global modeNames
 global funcs
 #mode=mode+1
 #check to make sure the newly selected mode is enabled
 tmp=0
 while(tmp<modeNum):
  mode=(mode+1)%modeNum
  if(sys.modules[modeNames[mode]].enabled=='True'):
   break #break on the first enabled mode we find
  #end if
  tmp+=1
 #end while
 HOTKEYS=keys[mode]
 HOTKEY_ACTIONS=funcs[mode]
 registerHotkeys()
 speak("Now in "+str(modes[mode])+" mode.")
#end def

#we now have the default mode to be used, but what if it is disabled?
if(sys.modules[modeNames[mode]].enabled=='False'):
 nextMode()
#end if

funcs=[]
#this dict MUST be defined after all the functions it uses have been
#ARM function dictionary
funcs.append({
  1 : exitProgram,
  2 : arm.sayLoad1,
  3 : arm.sayLoad2,
  4 : arm.sayLoad3,
  5 : arm.sayLoad4,
  6 : arm.sayProcAvg,
  7 : arm.sayUsedRam,
  8 : arm.sayDisk1Info,
  9 : arm.sayDisk2Info,
  10 : nextMode,
  11: clipboard.toClipboard
})

#weather function dictionary
funcs.append({
  1 : exitProgram,
  2 : weather.getCurrent,
  3 : weather.getToday,
  4 : weather.getTomorrow,
  5 : weather.getTwoDays,
  6 : weather.getThreeDays,
  7 : weather.switchLocation,
  8 : arm.sayDisk1Info,
  9 : arm.sayDisk2Info,
  10 : nextMode,
  11 : clipboard.toClipboard
})
funcs.append({
  1 : exitProgram,
  2 : network.speed,
  3 : arm.sayLoad2,
  4 : arm.sayLoad3,
  5 : arm.sayLoad4,
  6 : arm.sayProcAvg,
  7 : arm.sayUsedRam,
  8 : arm.sayDisk1Info,
  9 : arm.sayDisk2Info,
  10 : nextMode,
  11 : clipboard.toClipboard
})


HOTKEY_ACTIONS=funcs[mode]
